Abstract :
A programme using a matrix algorithm for deconvolution analysis of the renogram has been developed at the All India Institute of Medical Sciences, New Delhi. The programme plots the retention function for each kidney and computes minimum transit time, mean transit time and transit time index for them. Any prolongation of the transit time of the radioactive tracer through the various regions of the kidney becomes an important and reliable diagnostic tool for upper urinary tract obstruction
